This invention has for its object, the provision of a bobbin board of unusual strength, novel means being provided for supporting and reinforcing the rods which carry the pins whereby the bobbins are mounted.

A preferred form of the invention has been shown, but it is to be understood that a mechanic, working within the scope of what is claimed, may make such changes as his skill may suggest, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in a top plan, a bobbln board constructed in accordance with the invention;

Figure 2 is a section on the line 22 of the Figure 1;

Figure 3 is a perspective view of the rod which carries the pins;

Figure 4 is a perspective view of the channel member which is bent to form the casing;

Figure 5 is a perspective view of the reinforcing strip;

Figure 6 is a perspective view showing a portion of the completed cross-piece;

Figure 7 is a transverse section of the crosspiece shown in Figure 6, parts being broken away;

Figure 8 is a fragmental top plan, parts being broken away, and parts appearlng in section.

In carrying out the invention, there is provided a metal frame 1, which may be of the approximately rectangular form shown in Figure 1 of the drawings. Parallel crosspieces 2 extend across the frame 1 and have their ends engaged around the frame. The device includes other cross-pieces, designated as a whole by the numeral 4, the cross-pieces a 9 being disposed at right angles to the crosspieces 2. The cross-pieces L are composlte structures, and will be described in detail.

Each cross-piece 4 includes a rod 5, which, preferably, is half-round in cross-section. A

reinforcing strip 6 extends longitudinally of the rod. under the flat side of the rod, and is somewhat wider than the rod. The rod 5 is folded upon itself to form double-walled pins 7.

The rod 5 and the strip 6 are enclosed in a casing 8 having openings 9 through which the pins 7 extend. The casing 8 has a rib 10 which receives the rod 5, and the casi'ng'has flanges 11 which are overlapped on the under side of the reinforcing strip 6, in a way which will be readily understood when Figure 7 of the drawings is noticed. The casing 8, in its original form, is a channel member, as shown in Figure 4, the openings 9 being in the top 12 of the channel member and the top 12 being provided with sides 14 which are bent to form the flanges 11, the top 12 being distorted to form the rib 10.

The parts shown in Figures 3, i, and 5 may be pressed tightly together to form the cross piece shown in Figure 6. Referring to Fig ure 8, and noting numeral 15, it will be seen that both the rod 5 and the reinforcing strip 6 terminate short of the extremities of the casing 8, the end portions of the casing 8 being flattened and engaged as at 16 around the side portions of the frame 1. The completed article may be galvanized, tinned, soldered, spotwelded, or treated according to any other com mon process, in order to fasten the constituent parts of the device together and protect the metal from deterioration, it being understood that all parts of the article, preferably, are made of metal.

The article forming the subject matter of this application may be constructed cheaply, it possesses great strength, and is well adapted to stand the hard usage to which devices 0f this kind are subjected.

l/Vhat is claimed is 1. In a device of the class described, a rod provided with pins, a reinforcing strip extended longitudinally of the rod, and a casing enclosing the rod and the reinforcing strip and having openings through which the pins extend. 2. In a device of the class described, a rod provided with pins, a reinforcing strip eX- tended longitudinally of the rod, and a casing enclosing the rod and the reinforcing strip, the casing having openings receiving the pins, and the casing having flanges overlapped on the reinforcing strip.

3. In a device of the class described, a rod provided with pins, a reinforcing strip extended longitudinally of the rod and Wider than the rod, and easing enclosing the rod and the strip, the casing having flanges overlapped on the strip, and having a rib receiving the rod, the rib being provided with openings through which the pins extend.

4. In a device of the class described, a rod provided With pins, a reinforcing strip extended longitudinally of the rod, a casing enclosing the rod and the reinforcing strip and having openings through WhlCllthG pins extend, the strip and the rod terminating short of the extremities of the casing, and a frame, the end portions of the casing being engaged around the frame, independently of the rod and the strip.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

FRANK DAVIS.
